Description
Technical field
The present invention relates to the jaw type instrument, particularly electric power keeps in repair the special equipment of using with live line working of extracting spring catch.
Background technology
The common pincers of pulling pin are carrying out charged pulling pin during operation, because the bulb of pollution proof insulator is buried in insulator magnetic substance shirt rim, the insulator shirt rim has stopped entering of the general pincers of pulling pin, and this gives is live line working, be work high above the ground again, and the operation of pulling pin has brought very large difficulty.Simultaneously, the existing pincers of pulling pin are to the power of holding that the power of holding relies on the people fully that adds of insulator spring catch, and chucking power is little, clamping is difficult to firm lasting disadvantage so exist.
Summary of the invention
The purpose of this invention is to provide that a kind of clamping is firm, dependable performance, antifouling pin removal easy to use.
The object of the present invention is achieved like this: a kind of antifouling pin removal, comprise the pincers of pulling pin, and it is identical also to have structure, the left support abutment of left and right symmetric arrangement and right support abutment, wherein, right support abutment is welded on the tube coupling by an otic placode and constitutes, and has a bar shaped notch on this tube coupling; The left and right handle that clamps of pulling pin all is " Z " oxbow shape, pull pin pincers left handle and the otic placode of left support abutment fix, pull pin pincers right handles and the otic placode of right support abutment fix, be fixedly connected with an extension spring between the otic placode of left support abutment and the otic placode of right support abutment, intert among two tube couplings of left and right bearing with the taking-over activity ground that connects insulating tool, take on two outer ends of stretching out tube coupling and be provided with screw thread and sealing; Left and rightly in the adapter be connected with two housing screws symmetrically, and two housing screws are crimped on correspondingly respectively on two bar shaped notches on two tube couplings of left and right bearing.
Bar shaped notch on the above-mentioned tube coupling is oblique bar shaped notch, and the angle of the center line of this slant notch and the axis of this tube coupling is an acute angle.
The otic placode of above-mentioned right support abutment is the ears plate, and right handles is fixed between the ears plate through steady pin.
Also be fixed with a pivot pin on the ears plate of above-mentioned right support abutment; Extension spring connects firmly respectively on two pivot pins on the left and right bearing.
Compared with prior art, the present invention has following characteristics and advantage: when not being subjected to external force, the left side of pulling pin and clamping, right handles is under the extension spring effect, make two jaws be closure state or part state (spring catch can not stretch between two gaps between the jaw) a little, when operation is pulled pin in use, outwards draw back after left support abutment in the adapter and right support abutment overcome spring force being enclosed within, two jaws are opened and be clipped on the spring catch to be extracted, at this moment, eliminate external force, because the effect of extension spring, make a left side, right support abutment is drawn close mutually, simultaneously, two jaws are closed up gradually, thereby tightly spring catch is clamped.At this moment, two housing screws are inserted among the bar shaped notch on the left and right bearing, are screwed on the screw of adapter and compress maintenance, because the bar shaped notch is oblique layout, housing screw can be fixed left and right bearing in certain spacing range, that is to say two jaws are opened arbitrarily within the specific limits, with the clamping operation of the spring catch that adapts to different-diameter.
On the basis of common live line working bar point pin removal, improve, left and right handle is " Z " oxbow shape, and consider to change partial structurtes, make pin removal can enter bulb, a bowl junction, light installation and the dismounting spring catch of pollution proof insulator smoothly.Simultaneously, this pin removal considers that also suspension clamp the rim of a bowl difference still can solve spring catch towards, same pin removal and install and the dismounting problem.
The applicant was since 2010 05 month, and the development of carrying out the antifouling pincers of pulling pin improves, and has developed pin removal of the present invention, it can be installed and remove the pollution proof insulator spring catch smoothly, alleviate working strength, increase work efficiency, reduce the interruption duration of changing insulator.Through two months time and up to a hundred time scene on probation, these pincers of pulling pin can be than choosing more smoothly and recovering the spring catch of pollution proof insulator.
The designing and manufacturing level of this pin removal satisfies the requirement of " live line working general technical specifications ", and perfect in shape and function, dependable performance, easy to use, versatility is extensive, is applicable to the charged assembling and disassembling of pollution proof insulator and common insulator spring catch in the power industry, can improve the live line working rate.
Description of drawings
Fig. 1 is a front view of the present invention.
Fig. 2 is the upward view (vertical view and upward view symmetry) of Fig. 1.
Embodiment
Fig. 1, Fig. 2 illustrate, and the present invention pulls pin, and to have structure identical for pincers 1, the left support abutment 3 of left and right symmetric arrangement and right support abutment 2, and wherein, right support abutment 2 is welded on the tube coupling by an otic placode and constitutes, and has a bar shaped notch 2a on this tube coupling; Pincers 1 the left and right handle of pulling pin all is " Z " oxbow shape, pull pin pincers left handle 1b and the otic placode of left support abutment fix, pull pin pincers right handles 1a and the otic placode of right support abutment fix, be fixedly connected with an extension spring 5 between the otic placode of left support abutment and the otic placode of right support abutment, intert versatilely among two tube couplings of left and right bearing with the adapter 6 that connects insulating tool, take over 6 and stretch out on two outer ends of tube coupling and be provided with screw thread and sealing; Left and rightly in the adapter be connected with two housing screws 8 symmetrically, and two housing screws are crimped on respectively on two bar shaped notches on two tube couplings of left and right bearing (among Fig. 1 correspondingly, rear portion eyes front from the pincers of pulling pin, judge that it is left and right, perhaps, Fig. 1 is rotated counterclockwise 90 °, judges left and right handle).Bar shaped notch 2a on the tube coupling is oblique bar shaped notch, and the angle of the center line of this slant notch and the axis of this tube coupling is an acute angle.The otic placode of right support abutment 2 is the ears plate, and right handles 1a is fixed between the ears plate through steady pin 4.Adopt the ears plate can increase mechanical strength, simultaneously, be convenient to the fixing of left and right handle and spring.Also be fixed with a pivot pin 7 on the ears plate of right support abutment; Extension spring 5 connects firmly respectively on two pivot pins on the left and right bearing.
This pollution proof insulator pin removal satisfies " live line working general technical specifications ", is divided into two aspects of mechanical performance and electric property.Wherein electric property is subjected to the influence of pin removal structure very big.When calculating live line working Work tool effective and safe length, consider the margin of safety of 0.3m, this nargin is exactly the length of metal part short circuit air gap, directly influences the safety of operating personnel and equipment.Therefore, the bulk of whole pin removal can not surpass this value, this pin removal total length 230mm.
Mechanical properties, the pollution proof insulator pin removal is not very high to the requirement of strength of steel, but will consider processing technology.The jaw of assembling back pin removal should be adorned flexibly no jam phenomenon on axle.To consider the convenience of operating on the other hand.Jaw should be too not loosening with cooperating of axle, increases operating personnel's operation easier.
